The TWC-NV is the worthy successor to Tucor’s powerful and flexible TWC Flowmaster line, still based on Tucor’s proven 2-wire technology. The NV continues all of the irrigation control concepts and features of the TWC, and adds a number of enhancements; it takes advantage of significant improvements in modern electronics technology; and it is encased in a robust NEMA housing. It is directly compatible with all TWC components.

The TWC-NV requires only 2-wires to control up to 200 valves, up to 7 miles away. This remarkable feat is accomplished by connecting a uniquely-addressed decoder to the 2-wire path; the decoder is also connected to the valve. Turning on the decoder then turns on the valve: up to ten at the same time!
